Accountable Redemption API

openapi: 3.2.0
info:
  title: Accountable NAV / Proof of Reserves Feeds Redemption API
  version: '1.1'
  description: High-availability API providing real-time collateralization, net asset value (NAV), and redemption rate data with ripcord signalling for on-chain consumption by Chainlink. Endpoints can be queried directly from the source node and carry cryptographic guarantees (TEE attestations + HTTP Message Signatures per RFC 9421) for the integrity of the data. Accountable central nodes route to the underlying distributed network, provide fault tolerance across three clouds, and forward the cryptographic guarantees for the source data.

  note: Derived faithfully from Accountable's published "NAV / Proof of Reserves Centralized Endpoint" documentation (Version 1.1, March 2026). Field names, types, and descriptions are taken verbatim from the docs. No values were fabricated. The API is served from Accountable's distributed node infrastructure (per-client source nodes routed by central nodes across AWS, Google Cloud and Azure); the public base host is per-deployment, so the server below is templated.
